How much corrosion is too much?

Hello everyone, I am a new iBOATS subscriber and I need a bit of advice. I recently purchased a 22' starcraft center console that I knew had some corrosion but after taking out the deck and foam I found the problem was a bit more that I had hoped. In the first two photos you will see the strakes and the corrosion along them, they are like this the entire length on both sides on all three. The next 3 photos are some of the holes through the hull along the strakes from the inside of the boat about 20 to 25 holes the size of pencil erasers. The next photo is the seam where the hull bottom attaches to the transom plate. And the last two photos are areas where the foam was stuck to the hull and the corrosion and pitting in those areas. (no through holes four areas about 8" x 12 to 18")

My question is: can this be repaired or is it to much corrosion?

Thank you for your advice in advance. If you need to know more please ask and I will do my best to answer.

Anything man made can be remade. However that is a lot of corrosion

Either its a salt water boat, there is a bonding issue, or its sitting on green treated wood.

How thin is the hull where its pitted thru?

No treated wood here it has a roller trailer, this is pure galvanic corrosion (hope I spelled that correctly) from being in the Bay, and having the anode painted over.
the hull is 1/8 inch I am not sure how deep the corrosion is it is pitted with some spots that I can tell are about 1/32 to 1/16 deep.

Hate to say it, with that much damage, that one might not be cost effective to redo.

Thank you for your reply! My question then would be what should I do if I want to begin such a project? Can I weld the holes closed and clean up the pitted areas or does it have to come out?
